Examination of Temporal Characteristic of Wavelet Subbands of Scalp Epileptic EEG Based on the Local Min-Max
نویسنده
چکیده
In this paper, the temporal characteristic of wavelet subbands of scalp EEG of an epilepsy patient associated with different states of the brain is examined using the so-called number of local min-max. The computational results show that during the seizure onset the number of local min-max of the D1 subband extremely increases while the number of local min-max of the A3 subband remarkably drops. In addition, there are significant differences in the number of local min-max of epileptic EEG during the epileptic seizure event compared to other brain states. This suggests that the number of local min-max may be used as a useful feature for epileptic seizure detection.

متن کاملPrediction of Epileptic Seizures in Patients with Temporal Lobe Epilepsy (TLE) based on Cepstrum analysis and AR model of EEG signal
Epilepsy is a chronic disorder of brain function caused by abnormal and excessive electrical neurons discharge in the brain. Seizures cause disturbances in consciousness that occur without prior notice, so their prediction ability, based on EEG data, can reduce stress and improve quality of life. An epileptic patient EEG data consists of five parts: Ictal, Inter-Ictal, pre-Ictal, Post-Ictal, an...

Predicting the onset of epileptic seizure is an important and di$cult biomedical problem, which has attracted substantial attention of the intelligent computing community over the past two decades. We apply recurrent neural networks (RNN) combined with signal wavelet decomposition to the problem. We input raw EEG and its wavelet-decomposed subbands into RNN training/testing, as opposed to speci...
متن کاملAlterations of the electroencephalogram sub-bands amplitude during focal seizures in the pilocarpine model of epilepsy
Introduction: Temporal lobe epilepsy (TLE) is the most common and drug resistant epilepsy in adults. Due to behavioral, morphologic and electrographic similarities, pilocarpine model of epilepsy best resembles TLE. This study was aimed at determination of the changes in electroencephalogram (EEG) sub-bands amplitude during focal seizures in the pilocarpine model of epilepsy. Analysis of thes...
